HEEL-BURNISHING MACHlNE.

EPECIFICATION forming part of Letters'Patent No. 298,484, dated May 13,1884-.

Application filed October 17, 1883. (No model.) 7

To all whont it may concern:

Be it known that I, ISIDORE LEGAY, of the city, county, and State of NewYork, have invented a new and useful Improvement in Heel- BurnishingMachines and I do hereby declare that the following is a full and exactdescription thereof, reference being hadto the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

My invention relates to that class of shoeheel-burnishing machines. inwhich the shoe is supported upon an oscillating shaft in suitableposition to bring the heel of the shoe in line for contact with anadjustable burnishing or finishing tool.

The object of my invention is, first, to facilitate the attachment ofthe shoe to the oscillating shaft; second, to produce an automaticbearing of the burnishing-tool upon the heel; and, third, to permit thetool and its guide and frame to be swung out of the way, so that theburnished heel may be readily finished upon the machine by anapplication of hand-tools where required; and it consists in theconstruction and adaptation to these ends of the mechanism hereinafterdescribed and claimed. I

In the accompanying drawings, Figure l is a perspective view of myimproved machine complete. Fig. 2 is an enlarged view of theburnishing-tool, and Fig. 3 is an elevation of the movable stay-blockwhich actuates the burnisher and its gearing detached.

A A A represent a suitable base and standards, upon which is mounted anoscillating shaft, B. An oscillating movement is imparted to this shaft13 by means of a cog wheel, 0, fitted thereon, and which is interposedbetween toothed racksD D, adapted to reciprocate freely between suitablevertical guides arranged on opposite sides of the wheel, and to engagethe same. To one of these racks, D, is suspended a weight, D. The lowerend of the opposite rack, D, is connected by means of a cord or rod, Dwith a treadle, E. The pressure of the operators foot, when applied tothe treadle IE, will serve to counterbalance the suspended weight D",and to produce, by the operation of the treadle, an alternatereciprocation of the two racks DD, which will operate to produce anoscillation of the shaft B. One end, B, of the shaft is made to projectbeyond its bearings, and upon this projecting end is fitted a slidingcollar, F, carrying a dog or clamping-arm, F, adapted to project beyondthe end of the shaft, in line parallel therewith, and which is so bent,as shown in Fig. 1, as to permit of the insertion of a shoe upon the endof the shaft inside of said arm. The free end of the clamping-arm or dogF is carried upward, so as to bring it into line with the axis of theshaft, andit terminates in athreaded nut, F through which works athreaded clamping-bolt, F, whose axis coincides with the axis of theshaft 13. The end of this clamping-bolt F projecting toward the mainshaft terminates in a disk presenting a fiat surface perpendicular toits axis. The opposite end of the bolt is fitted with a crank orhand-wheel, F, for its rotation. The sliding collar F, by which the dogor clamping-arm is supported upon the shaft B, is secured, whenadjusted, by means of a setscrew, F

The burnishingtool and the movable stayblock by which its position uponthe heel is adjusted are supported by means of a frame carried upon theupper free end of an arm, G, pivoted to swing in a plane at a rightangle to the axis of the shaft B upon a vertical rod, G mounted upon astandard, G, supported upon the base A of the machine in line with thestandards A A, and the oscillating shaft B, supported thereby. The rod Gis made adjustable vertically in the standard G by means of acapstan-headed screw, a, fitted to the lower end of the rod with asocket-joint, and which works in a tubular threaded seat or recess inthe upper end of the standard. The arm G is guided in its vibration bymeans of a plate, G, attached at its lower end to the upper end of thevertically-adjustable rod G in a plane at right angles to the axis ofthe shaft B, and against which the arm swings under a parallel bar, 12,secured to the upper end of the plate, as illustrated in Fig. 1, the

arm being pivoted at its lower end to the face of the plate G",immediately over the top of the rod G", so as to admit of being broughtinto a vertical. position coincident with the axis of said rod and inline with the axis of the shaft 13, and to swing out thence to an angleof forty-five degrees, more or less. The

a shaft, H, is mounted in suitable bearings.

parallel with the shaft 13, and by the vibration of the arm G this shaftmay be brought into a position directly over the prolonged axis of theshaft B. Upon the body of this shaft H is mounted a cog-wheel, I, firmlyattached thereto, and the face of this wheel, in line parallel with itsaxis, is equal to or greater than the height of the shoe-heels to beburnished. The shaft II is adapted to traverse longitudinally in itsbearings, and it is threaded at its inner end to engage a threadedseatin its inner bearings, so that it shall be fed for ward or backwardtherein by its simple rotation. Its rotation is produced by means of asecond cogwheel, J, of a larger diameter than the cog-wheel I, and whichis mounted in the same frame to gear into said wheel, and is actuated bymeans of a hand-wheel or crank, J placed upon the end of its shaft.

A stay block or plate, K, is supported upon the ends of two parallelrods, K K, which are arranged to slide in line parallel with the shaftII through bearings in the frame which carries the wheels I and J. Thisblock K is moved backward and forward over the heel of the shoe, when itis clamped to the end of the main shaft B, by the reciprocating movementof the screwshaft II, whoseinner' end engages a socket in the end of theblock.

Attached to the frame upon the upper end of the arm G, and projectingupward therefrom, is an arm, L, terminating at its upper end in athreaded nut, L, through which works a transverse bolt, M. Upon one endof this horizontal bolt is formeda hand-wheel,

M, and to its opposite end anannular plate or I disk, M is attached witha pivot-joint. (See Fig. 1.) Through this annular plate M as a collar, aweighted rod, N, passes loosely, and terminates at its lower end in aweight, N, in

the lower side of which is formed a socket adapted to receive the shankof the burnishingtool 0. By an adjustment of the weighted rod N and ofthe horizontal screw-bolt M the disk M may be brought in proper positionover the heel of a shoe clamped upon the end of the main shaft 13, sothat the tool will drop and rest automatically with its full weightsmooth and the angles neatly rounded, to present a polishing-surface tothe heel to be operated upon.

In operating my improved machine the shoe, either with or without alast, is placed over the projecting end B of the main shaft B, with theheel out, and the clamping-arm or dog F is moved inward nn til the diskon the end of its clampingbolt F rests against the outer end of the heelof the shoe. The clampingarm is then made fast by means of the setscrewThe bolt F" is then-screwed up until the shoe is firmly held against theend of the main shaft, so as to rotate therewith. If, now, the arm G beswung into position to bring the lmrnishing-iron O, clamped to theweighted rod N, in position, with its V-shaped notch embracing andresting upon the front edge of the heel of the shoe, and the movablestayblock K is carried forward against the lower end of the burnisher Oas it thus rests on the edge of the heel, the machine is ready for theoperation of burnishing. An oscillating motion being imparted to the'main shaft B by means of the treadle and the racks D D, the shoe is madeto rotate reciprocally, the burnisher bearing thereon with its fullweight added to that of its weighted rod N. Meantime the burnisher ismade to traverse back. ward and forward upon the heel by means of theplate or rest K, which, being carried forward by the rotation of thescrew-shaft H through the agency of its operating-wheels I J and crank Jwill move the burnisher back over the heel, and, being withdrawn, willallow it to slide forward by reason of its weight over the slope of theheel. WVhen the heel is sufficiently polished by the burnishing-iron,the latter is removed, and the arm G, carrying the stay-plate K, isunclamped and swung back out of the way, so that a finishing-tool may beapplied by hand to the still rotating heel.

I reserve the right to cover the burnishingtool formed with a V-shapedrecess in its lower edge, to rest upon and embrace the curve of theshoe-heel, in a future application for Letters Patent; and

I claim herein as my invention- 1. In a shoe-heel-burnishing machine,the combination, with the oscillating main shaft, of an adjustable shoeclamp or dog fitted upon the end of said shaft by means of a slidingcollar encircling the shaft and fixed by a clamping device,substantially in the manner and for the purpose herein set forth.
